SPECIFICATION forming part of Letters IPatent No. 602,051, dated April 12, 1898.

Application filed June 15,1897. Serial No. 640,869. (No model.)

To all whom it may concern.-

Beit known that I, JosEPHA. BLACK, a citizen of the United States, residing at Parnell, in the county of Iowa and State of Iowa, have invented certain new and useful Improvements in Window-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window-fasteners;

and it consists in the novel construction and this invention.

window-fastener and a portion of the windowcombination of the parts hereinafter fully de-' scribed and claimed.

In the drawings, Figure 1 is a side view of portions of a window-sash and a windowframe provided with a fastener according to Fig. '2 is a front view of the frame. Fig. 3 is a sectional plan view taken on the line 00 0c in Fig. 1. Fig. 4 is a front view of the sockets on the window-sash.

A is a portion of a window-sash provided with a pane of glass in the usual manner.

B is a portion of the window-frame provided with guides 11, between which the window-sash slides. The window-sash is provided on its edge with a series of sockets G, which are let into it at'short distances apart.

D is the window-fastener, which consists of a pawl which works in a bracket d, let into the window-frame opposite the side edge of v the window-sash and between the guides 19.

The pawl or fastener D is journaled in a hole in one side of the bracket d, and it is provided with a lateral projection d for engaging with the sockets on the window-sash.

E is a small rod secured into the end of the fastener D and projecting through a hole in the window-frame. A plate e is securedto the front face of the window-frame for the rod to turn in, and e is a handle on the end portion of the rod for operating it. The handle When the pawl is in engagement nally, so that the projection d of the pawl passes from under the vertical recess f, in which it is normally free to work, into a horizontal recess f in the bracket 01. In this position the pawl cannot be raised and it then operates to lock the window-sash. When the pawl is not in the recess f, the window-sash can be raised, but it cannot belowered until the pawl is held up by means of the handle which is practically inaccessible from the outside of the window, the window-sash cannot be raised from the outside after the pawl has been slid into the recess f.

Both the upper and lowersashes of the window are provided with similar fasteners, but the rod which works the upper pawl is longer than the rod that works the lower pawl.

What I claim is j 1. In a Window-fastener, the combination, with a bracket carried'by the window-frame and provided with a vertical recess f and a horizontal recess f, of a longitudinally-slid able pawl journaled in the said bracket and free to oscillate in a' vertical plane while under the recess f, and means for sliding the said pawl into the recess f whereby it is prevented from oscillating, substantially as set forth.

2.. In a window-fastener, the combination, with a bracket carried by the window-frame and provided with a vertical recess f and a horizontal recess f, of a longitudinally-slidcured to the said rod and operating to depress the said pawl, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
